Analytical modelling of the effect of noise on the terahertz in-vivo communication channel for body-centric nano-networks
Publication date: Available online 4 May 2017 Source:Nano Communication Networks Author(s): Rui Zhang, Ke Yang, Qammer H. Abbasi, Khalid A. Qaraqe, Akram Alomainy The paper presents an analytical model of the terahertz (THz) communication channel (0.1 - 10 THz) for in-vivo nano-networks by considering the effect of noise on link quality and information rate. The molecular absorption noise model for in-vivo nano-networks is developed based on the physical mechanisms of the noise present in the medium, which takes into account both the radiation of the medium and the molecular absorption from the transmitted signal. T...

Study of hybrid and pure plasmonic terahertz antennas based on graphene guided-wave structures
Publication date: Available online 4 April 2017 Source:Nano Communication Networks Author(s): Seyed Ehsan Hosseininejad, Eduard Alarcón, Nader Komjani, Sergi Abadal, Max C. Lemme, Peter Haring Bolívar, Albert Cabellos-Aparicio Graphene is a unique material for the implementation of terahertz antennas due to extraordinary properties of the resulting devices, such as tunability and compactness. Existing graphene antennas are based on pure plasmonic structures, which are compact but show moderate to high losses. To achieve higher efficiency with low cost, one can apply the theory behind dielectric resonator antenna...

Releasing rate optimization in a single and multiple transmitter local drug delivery system with limited resources
Publication date: Available online 21 March 2017 Source:Nano Communication Networks Author(s): Shirin Salehi, Naghmeh S. Moayedian, Simon S. Assaf, Raul G. Cid-Fuentes, Josep Solé-Pareta, Eduard Alarcón Drug delivery is one of the most important applications of molecular communication. Drug transmitters have limited resources in terms of energy and reservoir and these limitations should be taken into consideration when designing a drug delivery system. Drug molecules may also be expensive and releasing a large amount of them can have harmful effects on the healthy parts of the body. In this paper, we consider a m...

Nature inspired node density estimation for molecular nanonetworks
Publication date: Available online 3 March 2017 Source:Nano Communication Networks Author(s): Taqwa Saeed, Marios Lestas, Andreas Pitsillides The problem of estimating the node density in ad hoc networks is a significant one for protocol design. In molecular nanonetworks, the node density estimation problem poses additional challenges due to the limited processing and communication capabilities of the network nodes which necessitate the design of simple to implement distributed solutions, and the diffusion based communication channel which is different from traditional electromagnetic networks. In this work, inspired ...

Towards cell-based therapeutics: A bio-inspired autonomous drug delivery system
Publication date: Available online 8 February 2017 Source:Nano Communication Networks Author(s): Chieh Lo, Kartikeya Bhardwaj, Radu Marculescu Traditional drug delivery systems are often inefficient and imprecise as they mainly rely on diffusion processes. For example, the blood circulation system is often used to transport and deliver drugs throughout the body; due to the randomness involved in molecular diffusion, this approach can cause inefficient and imprecise delivery of drugs. To address this problem, we propose an autonomous and adaptive bacteria-based drug delivery system that integrates bacterial chemotaxis ...

nanoNS3: A network simulator for bacterial nanonetworks based on molecular communication
We present nanoNS3, a network simulator for modeling Bacterial Molecular Communication (BMC) networks. nanoNS3 is built atop the Network Simulator 3 (ns-3). nanoNS3 is designed to achieve the following goals: 1) accurately and realistically model the real world BMC, 2) maintain high computational efficiency, 3) allow newly designed protocols to be implemented easily. nanoNS3 incorporates the channel, physical (PHY) and medium access control (MAC) layers of the network stack. The simulator has models that accurately represent receiver response, microfluidic channel loss, transfer rate and error analysis, modulation, and amp...

Time-slotted transmission over molecular timing channels
Publication date: Available online 7 February 2017 Source:Nano Communication Networks Author(s): Yonathan Murin, Nariman Farsad, Mainak Chowdhury, Andrea Goldsmith This work studies time-slotted communication over molecular timing (MT) channels. The transmitter, assumed to be perfectly synchronized in time with the receiver, is required to send K bits to the receiver using K information particles. It releases a single information particle in each time-slot, where the information is encoded in the time of release. The receiver decodes the transmitted information based on the random time of arrivals of the information ...

Electrochemistry for bio-device molecular communication: The potential to characterize, analyze and actuate biological systems
We describe an approach to access redox information through interactive electrochemical probing that is analogous to sonar. Tailored electrical inputs are coupled with diffusible redox mediators (electron shuttles) to access redox information in a local environment and generate complex but interpretable electrical output signatures. We use results from recent experimental demonstrations to illustrate the opportunity for redox to bridge bio-device communication. (Source: Nano Communication Networks)
